Below are sample questions representative of the exercises included on this worksheet and related 10.59 Gene Regulation and Cell Identity skill assessments:

Problem 1Difficulty: Mastery

Use the multi-omics table after a signal is added. Which gene is the strongest candidate for a direct signal-responsive target?

AGene A, because it has high methylation and low mRNA.

BGene B, because it has accessibility but almost no TF binding or mRNA response.

CGene C, because it has low methylation, high accessibility, high TF binding, and high mRNA after signal.

DGene D, because it has high methylation and no accessibility.

Solution & Explanation:A direct signal-responsive target should have accessible regulatory DNA, transcription factor binding after signal, and increased mRNA.

Problem 2Difficulty: Mastery

A scientist proposes editing a regulatory sequence in embryos to increase expression of a growth-related gene. Which concern is most directly tied to gene regulation?

AChanging a regulatory sequence could alter expression in unexpected tissues or developmental stages.

BRegulatory sequences cannot affect genes, so there is no biological concern.

CEmbryo editing only changes proteins after birth and never transcription.

DAll expression changes from regulatory edits are perfectly predictable.

Solution & Explanation:Regulatory DNA can control timing, location, and amount of expression, so edits may have broad or unintended developmental effects.

Problem 3Difficulty: Mastery

In random X-inactivation, ten independent precursor cells each have a 1/2 chance of leaving the maternal X active. What is the probability that exactly five of the ten leave the maternal X active?

A5/10, or exactly 50%

B1/1024, or about 0.1%

C10/10, or 100%

D252/1024, or about 24.6%

Solution & Explanation:Exactly five maternal-active cells can occur in C(10,5) = 252 arrangements, each with probability (1/2)¹⁰, giving 252/1024 or about 24.6%.
